Lets be honest, Spurs, Atletico and almost every other club outside of a select 6 or 7 are in that same boat and either sold as many or in some cases more world class level players, or just didn't have them to begin with. Dortmund sold (or lost) Gotze and Lewandowski, we sold Modric and Bale and Atletico sold Costa and Falcao.
Dortmund have spent the second most of any German team (including Wolfsburg), at over £100m in just 2 years, replacing and replenishing their stocks. Spurs trail about 6th for spending as far as English clubs go, with £140m in 2 years.
Nobody gives Spurs those excuses. If we slip to anything like Dortmund's level this season, Pochettino and Levy would be savaged on here for incompetence. Dropping to 18th (last) simply can't be excused by losing Gotze and Lewandowski and almost nothing else. Almost every other star player remains or remained at the club, including Reus and Hummels (despite injuries).
In a 34 game season, guys of varying levels like Sherwood, AVB, Redknapp and Pochettino could get 60 points almost without fail. Klopp's on course for less than 30 if this season finishes as it's started.
